Letters PatcntNo. 104,330, dated J unc`l4, LSTO.

The Schedule referred to in these Letters Patent and making part of che same To all vwhom it 'may concern:

Be it known that I, HENRY MAL'TH, a subject of thc Empire of France, but now a resident of New York, iu the city, county, and State of New York, have invented a new and useful Improvement iu Brick- 'Machines of which the following is a full, clear, and exact description, reference being had to the accompauyin g drawing forming part of this specification, and in which Figure l represents a pla-u of a brick-machine constructed in accordance with my improvement;

Figure 2, a front or side view ofthe same; Figure 3, a transverse section, taken as indicated by'the line x a; in iig. 2; and

Figure 4, 'an under view of the presser and cutters, detached.-

Similar letters of reference indicate corresponding parts. v

-My invention consists in certain combinations of devices or mechanism for making brick, in a rapid and perfect manner, from `the clay in a sheet, by the action of a constantly-reciprocating presser, with cutters attached, and intel-mittently-reciproeating bed, the clay being automatically sanded as it issues from the hopper to crushing-rolls, which operate, in conjunctionv A represents the frame, which may be made of cast- 1 B is an intermittently-reciprocating bed or platform, arranged to travel, by means of any suitable number of rollers, a a., on rails b b, secured to or forming part of the frame.

The platform is operated by a feed-screw, C, which is arranged under it, and works through a nut or box, D, secured to the platform, said screw turning in bearings at opposite ends, and, where it4 projects beyond one end of the fra-me, carrying four pulleys E E' F F', two of which, E and F, arc fast, and the other two, E and F', loose.

Motion is given to the screw C alternately, inv rcverse directions,'at suitable intervals, by means of a straight belt, G, and cross-belt G, by or from a drum, H, accordingly as said belts are shifted to rnn'on the fast or loose pulleys E E F F.

The object of -the fast and loose pulleys JJ is to secure tothe screw C an Aintermittent motion in its reverse actions on the platform, duringthe movement of the latter in 4both 'or opposite directions.

vThe shaft .h runs in hangers fi, and, near one of its extremities, is made to form acl-ank, y', that serves to secure continuous upand-down motion to a pitma-n, k, which works the presserand cut-ters or cuttingblock K, that slides up and down guide-rods t','and is divided, uponits under face, into any desired number of knives or cutting-partitions, l, of the sha-pc and size of the brick to be made.

Said cutting-block is arranged to play over thc platform B, where the latter is joined by a feedtable,'fL, disposed to lic at right angles to the platform.

On the revolving main shaft It are secured, by setscrews, two arms M M', which serve, as they strike in tiinely order thc lower bent ends of vertically-sliding bars'N N', connected by cords passing over pulleys, through eyes, with a horizontally-sliding belt-.shifting bar, O, to shift the beltHf/*t onto thc one or the other of the fast and looscfpulleys Jf J", and so to secure an intermittent motion to the screw C, in either or both A directions of its travel.

On the main shaft h are also arranged two other fastand loose pulleys l l, over either of which, accordingly as it is shifted, passes a belt, m., which serves to drive a pulley, Q, on the shaft of which is a pulley, R, that operates, by a belt, n, and pulley R', the one of a pair of pressing-rolls, S S, that press the clayas it is delivered from a hopper, T, and pass it on to the table L, which it is fed, in a shectform,'on to the platform or 011 to each one in succession of a series of loose plates or boards, U, placedthereon to receive the brick as it'is made by the cutting-block, and to facilitate ihetransfer of the brick, as made.

V V are sand-hoppers for holding and distributing sand on to the rolls and opposite sides ofthe clay passing therethrough, to prevent the clay' sticking to the rolls or 4other parts in its passagethrough the machine,

and to improve the manufacture of the brick.

The object of the fast and loose pulleys I l`V is to give an intermittent action to the feed ofthe clay, or arrest of thc feed at intervals, as required, and as here inafter described. p

The shifting of the belt m onto either pulley P P', alternately, to secure such intermittent action, is produced by arms M2 M3 on the shaft 71.,"acting, as they rotate, in a consecutive manner 011 the lower bent ends of a second pair of vertically-sliding bars, N2 N3, connected, by cords, with a horizontally-sliding belt-shifting bar, O'.

In the operation of the machine the clay is fed in a sheet, from over the table L, onto the plate or board U,.in Aline with it, and the cutting-block K descends to eut and form, or press a series of bricks, the platform B remaining stationary during such action, by the running of the driving-belt g* on the loose pulley J; but as the block K, with its knives, leaves the clay, the arm M acts upon the bar N to shift the belt on to the feed-pulley J, which gives to the platform a feed the distance of one set of molds or cutting-partitions, forward or backward, according to which of the belts, G or G', the platform B has last shifted ontok theirfast pulleys E or F. Each time the platform is thus moving the cutting-block continues to rise,'and makes a succeeding descent, but immediately before coming in contact with the clay again, the arm Ml acts upon the bar N to shift the belt g* ont-o the loose pulley J and to stop the motion of the'platform'.

This action is repeated continuously, and, by means ofthe arms M2 M3 acting successively on the bars N2 N3, a like timely intermittent action of the feed-rolls, relatively to the cutting-block, takes place, the feed stoppinfor when the knives of the latter are entering,r or leaving the clay, bythe shifting of the belt m onto the loose pulley P'. Thus the cutting-block K' moves continuously, while the feed of the clay and platform B is intermittent.

The reciprocating travel of the platform B, in being divided up into a succession of movements in both of its opposite directions, provides for the working or tilling with brick, in rapid succession, of a series of plates or boards U, from opposite sides of the cutting presserblock.
